Looking at a map of Europe ca. 1130 (when, between the Crusader states and the Kingdom of Georgia, the Christian presence in the east reached its post-Manzikert high point) the following political entities existed (roughoy grouped geographically):
England (ecluding, Ireland, Scotland, Wales, and including Burgundy and Normandy)
France (excluding the above)
Kingdoms of Norway (including a slice of the eat coast of Scotland), Denamrk, and Sweden (all separate)
Kingdoms of Leon & Castile, and Aragon & Navarre; the County of Provence-Barcelone (separated by a strip of coastal France); the Murabit Emriate (Southern Spain & Portugal and Moroccco).
The German Empire / HRE.
Kingdoms of Hungary; Poland; Principality of Russia; Volga Bulgars and Cumans to their east.
Byzantine Empire minus the breakaway Pruincipality of Serbia.
The Zirid Emirates (Tunisian Coast, bordering the Murabits).
The Fatimid Caliphate in Egypt.
PISA NOT GENOA controlling Corsica and Sardinia; Venice perhaps controlling Trieste (a VERY minor city at best ...)
Roger the Norman's Kingdom of Sicily controlling Sicily and southern Italy.
The Kingdom of Georgia, at its high point, surrounded by Alans in the north, and the Seljuk Sultanate of Hamadan to the south (the latter controlluing central Anatolia); to the east of the Seljuk Sultanate of Hamadan was the Seljuk Sultanate of Merv, stretching from the eastern shores of the Aral Sea to the southeastern shore of the Caspian.
... Plus of course the Crusader states and the Assassins of Alamut.
I hope that helps some

-- let me know if a different year and/or particular geopolitial presence is desired and I'll see what I can come up with.
Best,
